MOLD FOR CONCRETE WALLS.

SPECIFICATION forming part of Letters PatentNo. 713,173, dated November 11, 1902. Application filed May 10, 1902. Serial No. 106,739. (No model.)

To all whom it may concern:

Be it known that I,l HARRY A. TAYLOR, a citizen of the United States, residing at Jackson, in the county of Jacksonv and State of Miohigan,haveinvente'd certain newand useful Improvements in Molds for Concrete Walls; and I do hereby declare the following to beafull, clear, and eXact description of the invention, such as will enable others skilled in 1o the art to which it appertains to make and use the same.

My invention relates to improvements in molds for making concrete walls, and more especially to molds for making concrete Walls x5 for dwelling-houses and like structures; and its object is to provide convenient and ready means for molding said walls either plain or in imitation of stone or other masonry, to provide improved means for forming flues or 2o chambers in said walls, to provide ready means for adjusting the mold to form tapered or inclined walls, and to providel the deviceV with certain new and useful features hereinafter more fully described, and particularly z 5 pointed out in the claims.

My invention consists, essentially, in the improved framework to support the molds, together with the improved inner mold for forming the chambers or lues, and in certain' 3o details of construction, as will more fully appear by reference to the accompanying draw'- ings, in which- Figure lis a sectional perspective of a wall in process of construction, together with a de- 3 5 vice embodying my invention; Fig. 2, an enlarged detail of the outer angle of one of the outer triangular frames; Fig. 3, a plan of the same; Fig. 4, an enlarged detail of the upper angle of said frame; Fig. 5, a plan of the 4o same; Fig. 6, a detail in plan of the adjustable bracket to support the outer wall of the mold; Fig. 7, a perspective of an adjustable frame for inclined wall-surfaces; Fig. 8, an enlarged detail of the upper angle of the same;

Fig. 9, the same of the outer angle of the same; Fig. 10, the same of the inner angle of the same; Fig. 1l, the same of the extensionbrace of the same; Fig. 12, an enlarged detail of the molds in vertical section; Fig. 13,

5o details of the inner mold in plan view with parts broken away, and Fig. 14. a vertical section on the line 14 14 of Fig, 10.

Like letters refer to like parts in all of the figures.

A represents a Wall in process of construc- 5 5 tion; A', air chambers or iiuestherein'; B, ties connecting the respective portions of the wall opposite the chambers or iiues. To form these ilues orchambers, I provide plates C C, preferably of sheet metal. To these plates are at- 6o tached angle-bars Q, arranged horizontally on the plates and at such intervals as may be necessary to properly support the plates. The angle-bars overlap and slidably engage each other and at suitable intervals are provided with transverse slots Q', through which slots are inserted vertical rods C. Rigidly attached to these rods and at suitable places to engage and support the angle-bars Q are cams R, which cams serve also to space apart the 7o plates C C when turned with their longer axes at right angles thereto. Rigidly attached to the upper ends of the rods C are cross-bars C, adapted to engage the outer walls of the mold and support and locate the plates C C Y between the same and also'to serve as a lever to turn the rods C and cams R. When these cross-bars are turned parallel with the plates, the cams are also turned with their longer axes in the same direction and the plates are 8o then free to move toward each other and are thus released from contact with the wall and easily raised out of the flue or chamber and reset. f

The inner and outer walls of the mold are preferably of sheet-metal plates D and'D" and are supported in place by plank Vbacking D, as shown. These plates may be made heavy enough to dispensewith the planks, if preferred, and one or both plates may be 9o stamped to form a Wall-surface in imitation of brick or stone mason-work of any preferred design, as indicated at D". To permit ready release of the plates from the walls, I provide blocks or Wedges K between the planks and the supporting-frame, which blocks are first removed to release the mold from the wallsurface.

The inner wall o'fy the mold is preferably supported by triangular frames composed of roo a sill E', a post E, and a brace E, securely fastened together and detachably secured to the joists of the building by any suitable means, lag-screws E being shown herein. These inner frames and molds are preferably high enough to construct one story of the building at a time, being moved up and set again as each storyis completed. To support the outer walls of the mold, I provide triangular frames composed of posts F, sills F', and braces F, rigidly secured to each other, as shown, and adapted to be superposed one above the other. To level the lower frame, I provide an adjusting-screw L, which screw supports and vertically adjusts the outer angle of the lower frame to bring the post vertical. To secure the outer-angle of each frame and to provide suitable sockets for the outer posts I-I, which posts are adjustably inserted therein to support the superposed frames, I provide a socket consisting of a suitable piece of sheet metal folded twice at right angles and embracing the outer angle of the frame, as shown in Figs. 2 and 3. This socket is secured in place by suitable bolts G/ and extending above and below the sill F forms suitable sockets for the ends of the posts H. The upper angles of each frame in like inanner are provided with a sheet-metal socket I, embracing the upper angle of the frame and secured thereto by suitable bolts. The post F of each frame extends below the sill F' and rests on the post below, and the end of the brace F extends into the angle formed by the sill and post, as shown in Fig. 4:. It is also further secured by a removable bolt l.

On the posts F are vertically adjustable brackets J, formed of U-shaped irons, embracing the posts and adjustably secured in place thereon by bolts J and having their sides extended from the posts to engage and support the outer molds, which are horizontally movable on the brackets when the blocks or wedges K are removed. To secure the frames against lateral displacement, I provide suitable braces L', detachably connected to the frames by angle-plates and bolts.

To provide for inclining the outer surface of any one section of the wall, I provide adjustable triangular frames, as shown in Figs. 7 to ll, inclusive, in which the brace F is rounded and pivoted at its respective ends on the bolts G and I, as shown in Figs. 8 and 9, and the post F pivoted near the bottom on a bolt G and between plates P, attached to the inner angle of the frame. The brace F is also made longitudinally adjustable, as shown in Figs. 7 and 1l, by providing it with an overlapping and adjustable middle portion, on one part of which is journaled a pinion O, mounted in slidable hangers P and operated by a crank O'. This pinion engages a rack N in the other part ot' the brace, and this serves to adjust the total length of the brace, and thus adjust the inclination of the post of the frame. To rigidly secure the brace after adjustment, clips M, having binding-screws, are provided, which embrace and bind the overlapping parts of the same.

To adapt the inner mold to be used with outer walls of unequal heights, I provide the bar C with a shouldered end to engage the top and inner surface of the lowest wall and abut it against the highest wall at the other end.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l.
